...rubber 1. Natural rubber ( India rubber or caoutchouc ) is made from the latex of various plants by vulcanization which produces a tough, elastic material. Vulcanized rubber is natural (polyisoprene) rubber which has undergone curing (thermosetting) by a sulfur-vulcanization process or being subjected to high-energy gamma radiation. A similar process is used with styrene-butadiene rubber. It has a service temperature range −55 to +80°C. 2. Synthetic rubber consists of artificial polymeric substances, such as neoprene, that have similar properties to...

...positions are the opposite of those in first-angle projection, as are the plan and bottom views. The back view is again on the far right. First-angle projection is preferred in the UK and most of the rest of Europe, while third-angle projection is used in the USA, Australia and India. An oblique projection employs horizontal and vertical axes along which a component's actual dimensions are scaled, and an angled axis for receding depth along which the dimensions are often reduced to avoid the impression of distortion. In an isometric drawing (isometric...
